MACHINE FOR COOKIlING DOUGHNUTS.

Application filed April 16,

'To an whom it may concern:

Beit known that we, JAMES Murmur) COMB and CARLYLE EDWIN PEAVEY, cit zens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have .invented certain new anduseful Improvements in Machines for Cooking Doughnuts, of which the following is a specification. V p

Our invention relates to machines for cooking doughnuts and an object is to provide a machine for cooking or frying doughnuts in grease, or deep fat, without manual handling of the doughnuts. Another object is to provide a machine of this class, in which the doughnuts will be conveyed through hot grease contained in a receptacle and will be turned over during their progress through the receptacle so as to be unifc-rmly cooked on both sides. The full objects and advantages of our in vention will appear in connection with the detailed description'thereof, and the novel features embodied in our inventive idea will be. particularly pointed out in the claims.

In the drawings which illustrate the application of our invention in one form,-

Figure 1 is-a top plan view. Fig. 2 is a longitudinal view on the line 22 of Fig. 3.. Fig. 3 is a view on the line 33' of Fig. 2.

The support for the machine includes legs 10 and a table portion provided with a receptacle 12 for the rease or fat, underneath which is a gas burner 13 for heating the receptacle. The table is provided with bearing members 14, 1-6, 18, 20, 22, 24, 26 and 28. The bearing members and the support may be conveniently made as a solid casting. Shafts 30, 32, 34 and 36 are mounted in the bearing members. A sprocket wheel'38 is secured to the shaft 30 and a driving chain 40 runs over this sprocket. A sprocket wheel 42 is also secured to the shaft 30 and a sprocket chain 44 runs over this s rocket and over a sprocket 46 secured to t e shaft 32. The sprocket chain is pr vided with outstanding wire fingers 48, the chain being arranged to extend centrally and longitudinally over the receptacle tocarry the fingers along so that the ends, on a the lower travel of the chain, extend below the level of the hot grease in the receptacle.

A sprocket wheel 50' is secured to the shaft 32' and a sprocket chain 52 connects the Specification of Letters Patent.

sprocket wheel 50 with a sprocket wheel 54 secured'to the shaft 36 so that the latter is driven thereby. The chain 56, having Wire fingers 58 similar to the fingers 48, runs over a sprocket wheel 60 on the shaft 36 and a sprocket Wheel 62 on the shaft 38.-

Throughout this application the term doughnut is used broadly and is intended to cover any food article of like character.

The operation and advantages of our invention will be apparent from th' foregoing description. Doughnuts properly shaped are conveyed by-the belt 74 and de posited in the receivlng .end of the hot rease receptacle and are conveyed by the iingers 48 until they reach the paddle wheel located at, or near, the middle of the receptacle. The blades of the paddle-wheel push the doughnuts down one at a time and carry them around through one hundred eighty degrees, thus turning- -them over, whereupon they are taken by the fingers 58 and conveyed to the delivery end of the receptacle where the fingers lift them and deposit them onthe belt 78.

We claim:

1 A machine for cooking doughnuts comprising a receptacle for grease, means for heating said receptacle, means for conveying doughnuts partly through said receptacle, a paddle wheel for turning over the doughnuts, v and means for conveying the doughnuts through the remainder of said receptacle after they have been turned.

2. A machine for cooking doughnuts com- 4 3. A machine for cooking doughnuts comdoughnuts, and a conveyer belt for can-fling rising a receptacle for grease, means for 4 the cooked doughnuts away from said receplo Beating said receptacle, a conveyer belt for tacle, carryi-n the doughnuts to said receptacle, 7 In testimony whereof we hereunto aflix our 5 two en less chains having outstanding finsignatures.

gers for conveying doughnuts through said receptacle, a paddle wheel interposed be JAMES MAITLAND COMB. tween said chains v for turning over the CARLYLE EDWIN PEAVEY.
